Specific embodiment
Embodiment, refers to shown in Fig. 1, Fig. 2 and Fig. 3, a kind of time relay of the present utility model, including interface framework
4th, liquid crystal display 3, conductive bar 2 and pcb board 1, also including the keeper 5 between liquid crystal display 3 and pcb board 1, the keeper 5 sets
Have for contacting against the origin reference location face 521 in liquid crystal display, the elastic construction for being resisted against pcb board 1, for positioning conductive bar 2
Position limiting structure, keeper 5 installation before, the distance between the elastic construction top of keeper 5 and origin reference location face 521 are more than
The distance between the spacing of pcb board 1 and liquid crystal display 3 after installation, remaining structure top end and origin reference location face of keeper 5 are less than peace
The spacing of pcb board 1 and liquid crystal display 3 after dress.The liquid crystal display 3 and keeper 5 are spacing between interface framework 4 and pcb board 1, institute
State conductive bar 2 spacing between liquid crystal display 3 and pcb board 1, liquid crystal display 3 is electrically connected with pcb board 1 by conductive bar 2.It is described
Remaining structure of keeper 5 refers to other structures of the keeper in addition to elastic construction.
The keeper 5 includes side plate 53, and the height of side plate 53 is less than the spacing of pcb board 1 and liquid crystal display 3 after installing, such as
This can prevent the dimension overproof of other parts (for example：The clipping room of pcb board 1 and liquid crystal display 3 is away from too small) and lever press-in after,
Keeper deforms, and if too high, to liquid crystal display or the discontinuity of pcb board, there is risk.The elastic construction and
Position limiting structure is located at the relative both sides of the side plate 53.In the present embodiment, the elastic construction is lever elastic swing arm 54, fixed
Before position part is installed, the elastic swing arm 54 is away from the most significant end that one end top of position limiting structure is elastic swing arm, and and origin reference location
The distance between face 521 is more than pcb board after installation 1 and the spacing of liquid crystal display 3.The quantity tool of the elastic construction elastic swing arm 54
Body is two (quantity of the elastic swing arm 54 is not limited to two).Elastic swing arm 54 is near one end of position limiting structure and side plate
53 one are connected, and elastic swing arm 54 is provided with raised 541 upwards away from one end of position limiting structure, and the top of the projection 541 constitutes institute
State the top of elastic construction, i.e. before the installation of keeper 5, raised 541 top with and the distance between origin reference location face 521
More than pcb board after installation 1 and the spacing of liquid crystal display 3.In a pre-installation, each elastic swing arm 54 is in horizontality, and parallel, and
Raised the 541 of each elastic swing arm are contour.
In the present embodiment, the keeper 5 also includes base plate 52, and the base plate 52 is located at the bottom of the side plate 53, and is located at
Immediately below the elastic swing arm 54, the bottom surface of the base plate 52 constitutes the origin reference location face 521.
In the present embodiment, the position limiting structure is the stopper slot 51 of up/down perforation and lateral opening, and the conductive bar 2 is inserted
Stretched out respectively outside the upper and lower ends of stopper slot 51 in the two ends of the stopper slot 51, and the short transverse of conductive bar 5, conductive bar 2 will
Conduction, the height of the height more than stopper slot 51 of conductive bar 5, it is ensured that the short transverse of conductive bar 2 can be just carried out through overcompression
Two ends can form good contact with pcb board 1 and liquid crystal display 3 respectively.Width of the width D of the stopper slot 51 slightly larger than conductive bar 2
Degree, the length of the length L slightly larger than conductive bar 2 of the stopper slot 51, had both facilitated and had installed, and avoids conducting particles to pile up again and causes to lead
The low problem of the conductive reliability of electric bar 2.
During installation, conductive bar 2 is inserted vertically into the stopper slot 51 of keeper 5, liquid crystal display 3 is placed in interface framework 4
Inside bottom, the origin reference location face 521 of keeper 5 is contacted against on the back side of liquid crystal display 3, and pcb board 1 is placed in into keeper 5
The top of elastic swing arm 54, and liquid crystal display 2 is pressed in the keeper 5 for being equipped with conductive bar 2 using interface framework 4 and pcb board 1
Together, assembling is completed.It should be noted that the origin reference location face 521 of keeper arrives distance (keeper between elastic construction top
Before installation) have to be larger than liquid crystal display 3 and the spacing of pcb board 1 after installation, the top of remaining structure of keeper and its origin reference location face
The distance between 521 spacing for being then slightly less than pcb board 1 and liquid crystal display 3 after installation, are ensured effectively to fix liquid crystal display 3 and are protected with this
Shield liquid crystal display 3 is not subject to crushing.Before installation, each elastic swing arm 54 is in horizontality, after installation, the projection of each elastic swing arm 54
541 are pushed by pcb board 1, make elastic swing arm 54 occur elastic deformation and it is inclined.
Keeper of the present utility model 5, with certain elasticity, is fixing liquid crystal display using the elastic swing arm 54 of lever type
Liquid crystal display 3 is protected not to be subject to crushing while 3.Wherein：Distance of the most significant end of the elastic swing arm 54 of keeper to origin reference location face
(namely maximum height H of keeper) must be bigger than the distance between liquid crystal display after installation 3 and pcb board 1, can so play solid
Determine the effect of liquid crystal display 3, and liquid crystal display 3 is played a protective role with certain elasticity；The other positions height of keeper 5 must
The distance that must be slightly less than after installing between liquid crystal display 3 and pcb board 1 is small, is just avoided that assembling process damages liquid crystal display 3 by pressure.
The limited location groove 51 in the x direction of keeper 5, conductive bar 2 is positioned by the face where the width D of stopper slot 51,
So in a z-direction, conductive bar can be moved up and down more neatly.When installing pcb board 1, because the height H of keeper 5 is pressed
Contracting, produces a power vertically downward, and by the effect of lever type elastic swing arm 54, power will be broken down into the fixing force in z directions
With the power in x directions, the elastic force in wherein z directions is to fix liquid crystal display 3, and the power in x directions causes that keeper 5 is pasted with interface framework face 4
It is flat, reduce between keeper 5 and interface framework 4 gap so that the compression in a z-direction of conductive bar 2, will not be transmitted to x directions,
Conductive bar 2 is set to connect relatively reliable.
Above-described embodiment is only used for further illustrating a kind of time relay of the present utility model, but the utility model is not
It is confined to embodiment, it is every according to technical spirit of the present utility model structure of keeper in above example etc. to be made
Any simple modification, equivalent variations and modification, each fall within the protection domain of technical solutions of the utility model.
